ESAB DUAL SHIELD R-70 ULTRA Flux Core Wire, 3/32″, 60 lb Coil
This flux cored welding wire produces smoother arc characteristics and lower welding fumes than many competitive flux cored wires. Dual Shield R-70 Ultra is also designed to have a greater tolerance of mill scale and surface oxides. The notch toughness in the as welded condition is also improved. Bead contour is flat to slightly convex and slag coverage is complete. Dual Shield R-70 Ultra wire is designed for flat and horizontal single or multi-pass applications on low or medium carbon steels recommended with 100% CO2 shielding gas. Areas of application include railcar, heavy equipment, and general fabrication.
Features and Benefits
- ESAB pioneered the development of gas-shielded flux-cored welding (FCAW) in 1957. Today, ESAB offers the broadest variety of mild steel and low alloy flux-cored wires available anywhere in the world.
- ESAB cored wires offer flat welds with deep penetration and wetting into plate, with high deposition rates and efficiencies. This dramatically reduces weld time, increasing productivity.
- Flux-cored welding can be up to three times more productive than Stick and up to 2.5 times more productive than MIG. FCAW also offers productive positional welding and low diffusible hydrogen levels (H5) when required.
- ESAB Coreweld metal-cored wires were developed to meet the needs of demanding applications, such as structural steel construction, heavy equipment, transportation, bridges, petrochemical processing, offshore rigs, railcars, shipbuilding, pressure vessels, and general fabrication.
- Utilizing advanced manufacturing processes and specially formulated composite fillers, Coreweld metal-cored wires combine high deposition rates and efficiencies, high travel speeds, excellent penetration, and ease of use. Metal-cored wires also provide excellent arc stability and outstanding penetration and wetting, with superior fusion at the root joint and sidewall. The result is a high-quality weld with minimal slag and spatter, and fewer residual silica islands.
- Metal-cored wires offer several advantages over solid wire. Since metal-cored wires carry the current on the outer sheath, current densities are considerably higher than those found in wires sold, where the current is carried across the entire cross-sectional area. As a result, the metal-cored arc tends to be softer and can bridge gaps easier with reduced tendancy for burn through.
